I know this is an old topic but I bumped into it, and wanted to know if a physics expert could tell me if my solution to this problem is correct? Edit: Hmm I just subbed in my answer with the original values and the answers don't quite match up :/ What did I do wrong?

Ahhhh, a quadratic. Thanks! :D

Thanks, but...how am I to know how much to add to the height in (b)? Since the person drops from a higher position, it will be a larger number, right? I don't know what that number is, though, because that's what the whole equation is trying to solve. :/

EPE = 1/2kx^2 right? So for the 18m situation where i know x, would I use that to find k, then sub that into get x in the first question? That would make sense to me, but usually things that make sense to me in Physics are wrong. But anyway... GPE(o) = KE (which is zero) + EPE(f) mgh = 1/2kx^2...

Simple harmonic motion! :( Homework Statement A 65-kg person jumps from a window to a fire net 18m below, which stretches the net 1.1m. Assume that the net behaves like a simple spring, and (a) calculate how much it would stretch if the same person were lying in it. (b) How much would it...
